更严厉的知识产权保护制度有利于技术创新吗?

Do Stronger Intellectual Property Rights Promote Innovation?

本文将知识产权因素引入内生增长模型,分析了知识产权保护对技术进步的影响机制;再利用27个发达国家和57个发展中国家面板数据,检验开放经济条件下,知识产权保护与技术创新的系统关联,并为"最优知识产权假说"提供了跨国层面的经验证据。本研究发现知识产权保护总体上有利于一国技术创新,但更严格的知识产权保护对技术创新的影响取决于该国的初始保护力度,该结论在控制内生性问题后仍成立。进一步的研究发现,发达国家所适用的最优知识产权保护力度显著高于发展中国家。这一结果表明,发达国家实施的"国际统一知识产权保护制度"是不符合发展中国家实际利益的。

This paper follows the controversy regarding the effects of stronger intellectual property rights(IPR)on technological innovation under the North-South analytical framework.Using panel data from 27 developed countries and 57 developing countries,this study systemically examines the relationship between IPR and technological innovation after controlling for a potential endogenous problem.Our empirical results support the optimal IPR hypothesis.We find that the threshold effects of stronger IPR on innovation depended on the initial IPR level.Neither very strong IPR nor very weak IPR are conducive to innovation.Furthermore,the optimal level of IPR in developed countries is higher than that of developing countries;this difference implies that adoption of IPR standard of developed countries may be inefficient for developing countries.
